Colorblind question

For the CDL med test you only have to be able to tell the red or green of a traffic light.

I am color blind also but I could see the red green difference well enough to pass.

 

Your best bet is to ask a Dr that does the DOT physicals..

I spent some time researching your question but couldn’t really find a definitive answer.

 

Psst the top light is always Red. I'm also shaded color blind like tanker. They never chkd me for it.

 

Yes, it is legal to drive while colorblind in every state. ... They would not pass the driving test otherwise. Massachusetts is the only state in the US that specifically mentions color vision in its licensing requirements: “Drivers must be able to distinguish between the colors red, green, and amber.”

I could not find color blindness prohibiting CML in the FMCSA searches. The studies done seem to lean toward color blindness not having any significant outcome in accident studies.

If I'm incorrect, please show where its prohibited, but I could find it.

 

No you must pass a certain specific visual test to determine color in both eyes.

If you cannot with color blind, you will be excluded from trucking but not from car driving due to much looser rules.

§391.41 Physical qualifications for drivers.
(3) A person is physically qualified to drive a commercial motor vehicle if:
(10) Has distant visual acuity of at least 20/40 (Snellen) in each eye without corrective lenses or visual acuity separately corrected to 20/40 (Snellen) or better with corrective lenses, distant binocular acuity of at least 20/40 (Snellen) in both eyes with or without corrective lenses, field of vision of at least 70° in the horizontal Meridian in each eye, and the ability to recognize the colors of traffic signals and devices showing standard red, green, and amber;

 

Thank you for that, I have never been tested for color in a DOT examine, Good info.

 

If you can correctly identify the red bar and the green bar on the eye chart, you should be fine.

 

I am color deficient, different from color blind. Been driving truck for 53 years and never failed a physical. Like others have said, red green and yellow your good to go.
